DN197 Offset D Pull Handle

Application & Project Fit

The DN197 is specified across residential, commercial, and coastal door hardware programmes where a corrosion-rated pull handle with confirmed lock body compatibility is a project requirement.

Fabricators and builders specifying Doric mortice locks — the DN950, DN970, or DN1290 — can pair the DN197 directly as the external pull handle, completing a matched hardware set from a single manufacturer. For teams managing hardware schedules across multiple dwellings or tenancies, this eliminates the need to source and stock handles and locks from separate suppliers and simplifies procurement across varying project aesthetics.

For projects requiring a direct pull handle replacement on existing aluminium, timber, or glass doors, the DN197’s three standard sizes and back-to-back fixing arrangement suit a wide range of Australian door profiles without frame modification or custom routing.

The Offset D Profile — Ergonomics and Lock Clearance

The offset geometry of the DN197 is a specification feature, not just a design name. The handlebar is positioned 25mm proud of the mounting bracket, displacing the grip away from the door face for two distinct reasons.

The first is grip clearance. On doors fitted with an external lock cylinder or escutcheon, a flush or low-profile handle restricts the finger channel around the grip during operation. The DN197’s offset positions the hand further from the door face, producing a deeper, more natural grip that reduces operating effort on heavy or wide doors and suits high-frequency commercial use.

The second is installation compatibility. The 25mm offset creates the necessary clearance between the handle bar and any lock body, cylinder, or escutcheon mounted to the same door stile. This is critical when the DN197 is paired with a Doric mortice lock body, where handle and lock must share the door face without mechanical interference.

Material & Durability

The DN197 is manufactured from high-grade 304 stainless steel throughout — handle bar, bracket, and fixing plate. The corrosion resistance is inherent to the material specification, not dependent on a surface treatment that can wear through under high-cycle use or prolonged coastal exposure.

304 stainless steel is the recognised specification for exterior door hardware in Australian construction. It resists oxidation and surface corrosion across all Australian climates, maintains dimensional stability under repeated mechanical load, and provides UV stability without the colour fade or surface degradation that affects coated metal or polymer hardware over time.

Salt spray tested to 100,000 hours. This result, achieved under the ASTM B117 accelerated salt spray test protocol, confirms corrosion performance appropriate for any Australian coastal, marine, or tropical environment. For builders specifying into beachfront developments or waterfront commercial projects, this removes the risk of premature hardware failure and the callback liability that follows it.

Size Selection Guide

The DN197 is available in three sizes to suit different door widths and project types. Size selection is a specification decision based on door width, user requirements, and hole centre compatibility with the existing frame.

Back-to-back fixings are supplied with every DN197 unit. No separate fixing hardware is required for two-sided installations.

What lock bodies is the DN197 compatible with?

The DN197 pairs directly with Doric’s DN950, DN970, and DN1290 mortice lock bodies. The DN1290 is available in 30mm (DN1290/30) and 40mm (DN1290/40) backset options. This makes the DN197 the correct external pull handle for any door using these lock bodies, creating a completely matched hardware set from a single manufacturer. Compatible cylinders for the DN1290 configuration include the DS197, DS202, DS250, and DS1272.

What is the difference between the three DN197 sizes?

The three sizes differ in overall length and hole centre spacing. The 325mm (300mm centres) suits standard residential doors, the 425mm (400mm centres) suits wider residential and light commercial entries, and the 625mm (600mm centres) suits large commercial, institutional, and high-traffic entries where a longer grip surface and wider 80mm bar profile are appropriate for heavy doors.

Is the DN197 suitable for coastal environments?

Yes. The DN197 is salt spray tested to 100,000 hours using a 304 stainless steel body. This makes it the correct specification for coastal residential projects, waterfront commercial buildings, and any application where salt air, humidity, or marine spray is a permanent environmental condition.

Does the DN197 come with back-to-back fixings?

Yes. Every DN197 is supplied with back-to-back fixings, allowing two handles to be installed on opposite faces of the same door without sourcing additional hardware. This simplifies procurement and reduces on-site materials management for volume installation programmes.

Can the DN197 be powder coated to match my project colour schedule?

Yes. Powder coat finishes are available to order for Trade Account holders, allowing the DN197 to be colour-matched to project hardware schedules and aluminium door frame finishes. Contact Doric’s technical team with your colour specification for pricing and lead time.

Is the DN197 suitable for glass doors?

Yes. The DN197 suits aluminium, timber, and glass door applications. For glass door installations, confirm fixing compatibility with the glass thickness and mounting configuration with Doric’s technical team before ordering.

Does the DN197 require frame modification to install?

No. The DN197 uses standard hole centre spacing — 300mm, 400mm, or 600mm, depending on size — and back-to-back fixings that suit a wide range of standard Australian door profiles without modification. For retrofit installations on existing doors, confirm the existing hole centre spacing against the three DN197 size options before ordering.

What is the projection of the DN197 from the door face?

The DN197 projects 25mm from the door face at the mounting bracket. This offset provides full grip clearance without excessive protrusion and ensures compatibility with door lock cylinders and escutcheons mounted to the same door face when the DN197 is paired with a Doric lock body.
